Abstract

Reaction of [(3-bdppmapy)(AuCl)] with NaHmba (3-bdppmapy = ,'-bis-(diphenylphosphanylmethyl-3-aminopytidine, Hmba = 2-mercaptobenzoic acid) resulted in a new tetranuclear Au/P/S complex [(3-bdppmapy)(AuHmba)(AuCl)] (1). Upon excitation at 370 nm, 1 exhibited solid state, room temperature, green fluorescent emission (QY = 4.7%, = 2.58 ns) which was significantly enanced at lower temperatures due to strengthening of the Au-Au interaction. Different ratios of 1 with phosphor N630 in PMMA were used to make thermochromic photoluminescent films and fibres that could be fabricated into an optical thermometer sensitive over temperature ranges 80-300 K and 300-370 K.

摘要

[(3 - bdppmapy)(AuCl)]与NaHmba（3 - bdppmapy = ，'-双-(二苯基膦基甲基-3 - 氨基吡啶，Hmba = 2 - 巯基苯甲酸）反应生成了一种新的四核Au/P/S配合物[(3 - bdppmapy)(AuHmba)(AuCl)]（1）。在370 nm激发下，1在固态室温下呈现绿色荧光发射（量子产率 = 4.7%，寿命 = 2.58 ns），由于Au - Au相互作用增强，在较低温度下发射显著增强。将1与PMMA中的荧光粉N630以不同比例混合，用于制备热致变色光致发光薄膜和纤维，可制成在80 - 300 K和300 - 370 K温度范围内敏感的光学温度计。
